What do scientists hope to accomplish using recombinant DNA?
Ber [7]

The correct answer is: Replacement of defective genes with normal genes

Recombinant DNA molecules are made in laboratory by the methods of genetic recombination such as molecular cloning. The aim of these methods is to bring together genetic material from different sources, creating “combinations” that usually couldn’t be found in the genome. The process of recombination is possible because, DNA molecules from all organisms share the same chemical structure (nucleotides are same among different species, difference is only in the nucleotide sequence).

A group of students wants to study the rate of photosynthesis under various conditions. They use a blender to mechanically disru
11Alexandr11 [23.1K]

Answer:

B

Explanation:

The statement that best explains the result would be that <u>the rate of photosynthesis is greatest for direct sunlight and least for the infrared light.</u>

The DPIP will normally replace and play the role of NADPH in the light reaction of the process of photosynthesis. Hence, it will become colorless as a result of reduction and the rate of photosynthesis can be monitored based on the magnitude of the disappearance of the dark blue color.

It means that the more colorless the liquid in the illustration is, the more the rate of photosynthesis. <em>The color change moved from dark blue to clear colorless under direct sunlight, from dark blue to nearly colorless under indirect sunlight, and from dark blue to slightly lighter under the infrared light.</em> <u>This clearly indicates that the rate of photosynthesis is highest under direct sunlight and lowest under infrared light with the indirect sunlight having an intermediate rate. </u>

The correct option is B.

How would you describe symmetry in invertebrates?
vodomira [7]

Answer:

Invertebrates can have bilateral or radial symmetry, or they can be asymmetrical. Bilateral symmetry means that the animal is arranged in the same way on both sides. Radial symmetry means the body parts are arranged in a circle around a central point.
